SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation of this instrument. Failure to
comply with these precautions or with specific warnings elsewhere in this guide violates safety standards of design,
manufacture, and intended use of the instrument. Agilent Technologies assumes no liability for the customer's failure to
comply with these requirements.
GENERAL.
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective features of this product may be
impaired if it is used in a manner not specified in the operation instructions.
Any LEDs used in this product are Class 1 LEDs as per IEC 825-l.
This ISM device complies with Canadian ICES-001. Cet appareil ISM est conforme à la norme NMB-001 du Canada.
ENVIRONMENTAL CONDITIONS
All instruments are intended for indoor use in an installation category II, pollution degree 2 environment. They are designed to operate at
a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the specifications tables for the ac mains voltage
requirements and ambient operating temperature range.
BEFORE APPLYING POWER.
Verify that the instrument is set to match the available line voltage.
GROUND THE INSTRUMENT.
To minimize shock hazard, the instrument chassis and cover must be connected to an electrical ground. The instrument must be
connected to the ac power mains through a three-conductor power cable, with the third wire firmly connected to an electrical ground
(safety ground) at the power outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth
terminal will cause a potential shock hazard that could result in personal injury. If the instrument is to be energized via an external
autotransformer for voltage reduction, be certain that the autotransformer common terminal is connected to the neutral (earth pole) of the
ac power lines (supply mains).
FUSES.
Only fuses with the required rated current, voltage and specified type (normal blow, time delay, etc.) should be used. Do not use repaired
fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made by qualified
service personnel. Do not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even
with the power cable removed. To avoid injuries, always disconnect power, discharge circuits and remove external voltage sources before
touching components.
DO NOT EXCEED INPUT RATINGS.
This instrument may be equipped with a line filter to reduce electromagnetic interference and must be connected to a properly grounded
receptacle to minimize electric shock hazard. Operation at line voltages or frequencies in excess of those stated on the line rating label
may cause leakage currents in excess of 5.0 mA peak.
SAFETY SYMBOLS.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the
instrument. Return the instrument to an Agilent Technologies Sales and Service Office for service and repair to ensure that safety features
are maintained.
The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like, which, if not correctly
performed or adhered to, could result in personal injury. Do not proceed beyond a WARNING sign until the
indicated conditions are fully understood and met.
The CAUTION sign denotes a hazard. It calls attention to an operating procedure, or the like, which, if not
correctly performed or adhered to, could result in damage to or destruction of part or all of the product. Do not
proceed beyond a CAUTION sign until the indicated conditions are fully understood and met.
Instruments that appear damaged or defective should be made inoperative and secured against unintended operation until they can be
repaired by qualified service personnel.

General Information
Introduction
This is the operating manual for your Agilent Series 654xA, 655xA, and 657xA power supplies. Unless otherwise stated, the
information in this manual applies to all models in the series. These supplies are the analog-programmable counterparts of
the Agilent Series 664xA, 665xA, and 667xA GPIB System power supplies.
Safety Considerations
This power supply is a Safety Class 1 instrument, which means it has a protective earth terminal. That terminal must be
connected to earth ground through a power source equipped with a 3-wire ground receptacle. Refer to the Safety Summary
page at the beginning of this manual for general safety information. Before installation or operation, check the power supply
and review this manual for safety warnings and instructions. Safety warnings for specific procedures are located at
appropriate places in the manual.
Instrument Identification
The power supply is identified by a unique two-part serial number, such as 3343A 00177. The first part, or prefix, is a
number-letter combination that provides the following information:
3343 The year and week of manufacture or last significant design change. Add 1960 to the first two digits to determine
the year. For example, 33=1993, 34=1994, etc. The last two digits specify the week of the year (43 = the 43rd
week).
A The letter indicates the country of manufacture, where A = USA.

Each power supply is programmable locally from the front panel or remotely via a rear-panel analog control port.
Operational features include:
• Constant voltage (CV) or constant current (CC) output over the rated output range.
• Built-in overvoltage (OV), overcurrent (OC), and overtemperature (OT) protection.
• Automatic turn-on selftest.
• Pushbutton nonvolatile storage and recall of up to 5 operating states.
• Local or remote sensing of output voltage.
• Auto-parallel operation for increased total current.
• Series operation for increased total voltage.
• Analog input for remote programming of voltage and current.
• Voltage output for external monitoring of output current.
• User calibration from the front panel.

General Information
Front Panel Programming
The front panel has both rotary (RPG) and keypad controls for setting the output voltage and current. The panel display
provides digital readouts of the output voltage and current. Other front panel controls permit:
• Enabling or disabling the output.
• Setting the overvoltage protection (OVP) trip voltage.
• Enabling or disabling the overcurrent protection (OCP) feature.
• Saving and recalling operating states.
• Calibrating the power supply.
Analog Programming
The power supply has an analog port for remote programming. The output voltage and/or current of the power supply may
be controlled by d-c programming voltages applied to this port. The port also provides a monitor output that supplies a d-c
voltage proportional to the output current.
Output Characteristic
General
The power supply can operate in either CV (constant voltage) or CC (constant current) over its voltage and current ratings
(see “Performance Specifications”). The operating locus is shown by the output Characteristic Curve in “Supplemental
Characteristics”. The operating point is determined by the voltage setting (Vs), the current setting (Is), and the load
impedance. Two operating points are shown. Point 1 is defined by the load line cutting the operating locus in the
constant-voltage region. This region defines the CV mode. Point 2 is defined by the load line cutting the operating locus in
the constant-current region. This region defines the CC mode.
Downprogramming
The power supply can sink current for more rapid down programming in the CV mode. For Series 654xA and 655xA
supplies, this capability is defined by the second quadrant area (-Is) of the Output Characteristic Curve. These supplies can
sink about 20% of their maximum rated positive output current. For Series 657xA power supplies, this is an uncharacterized
current-sinking area that provides a limited downprogramming capability.
Specifications and Supplemental Characteristics

Maximum AC Line Current Ratings
200 Vac nominal:
230 Vac nominal:
Maximum Reverse Bias Current:
With AC input power applied and the dc output reverse biased by an external dc
source, the supply will continuously withstand without damage a current equal to its
output current rating.
Remote Sensing Capability
Voltage Drop Per Lead:
Load Voltage:
Subtract voltage drop in load leads from specified output voltage rating.
Up to 1/2 of rated output voltage.
Load Regulation:
Degradation due to load lead drop in -output: None
Degradation due to load lead drop in + output: ∆mV (regulation) = 2V
